Student Looking for Real Industrial PLC/HMI Problems to Practice

Hello everyone,


I am an electrical/automation student, and I am currently learning PLC programming and HMI design. I have some experience with small school projects, such as controlling motors, sensors, basic automation sequences, alarms, and simple HMI screens.


However, I realize that school projects are quite different from real industrial systems. I want to improve my practical thinking and understand how PLC programs are designed in real factories.


So I would like to ask the engineers here:


Could you share some real industrial PLC/HMI problems or project scenarios that you have worked on?


For example:

• Machine control sequences
• Conveyor systems
• Pump or motor control systems
• Alarm handling
• Interlocks and safety logic
• Auto/manual operation
• HMI screen structure
• Troubleshooting cases
• Communication between PLC, HMI, VFD, sensors, or other devices

I am not asking for confidential company programs or private documents. I just want to learn from realistic examples and practice solving problems like an automation engineer.


Any advice, sample requirements, or real-world scenarios would be very helpful for me.


Thank you very much.
